jQuery怎么获取mousedown的位置值，给mousemove使用？

图片说明
我这样简单实现移动会有什么问题和隐藏问题吗？

用这个函数

function getMousePos(event) {
            var e = event || window.event;
            var scrollX = document.documentElement.scrollLeft || document.body.scrollLeft;
            var scrollY = document.documentElement.scrollTop || document.body.scrollTop;
            var x = e.pageX || e.clientX + scrollX;
            var y = e.pageY || e.clientY + scrollY;
            //alert('x: ' + x + '\ny: ' + y);
            return { 'x': x, 'y': y };
   }
